Specially shaped gold nanoparticles have intrigued considerable attention becausethey usually possess high-sensitivity surface-enhanced Raman scattering (SERS) and thusresult in large advantages in trace biodetermination. In this article, starch-capped goldnanoparticles with hexagon and boot shapes were prepared through using a nontoxic andbiologically benign aqueous-phase synthetic route. Shap...
targeting riboflavin binding protein (RFBP), which acts as a model protein for the riboflavin receptor. By characterizing the binding interactions between riboflavin dendrimer gold nanoparticle conjugates and RFBP, the efficacy of this platform for a targeted approach of drug delivery can be predicted more accurately. Atomic Force Microscopy (AFM) was used for biological imaging studies of thes...
Photodynamic therapy has emerged as an effective therapeutic alternative to treat oncological, cardiovascular, dermatological, infectious, and ophthalmic diseases. combines the action of a photosensitizer with light in presence oxygen generate reactive species, capable reacting cellular components, resulting injury and, consequently, inducing death. Phthalocyanines are considered good photosens...
Abstracts: nanoparticles. All the extracts were used separately for the synthesis of gold nanoparticles through the reduction ofaqueous AuClgold ions to gold nanoparticles. The ethanol extract of black tea and its tannin free ethanol extract produced goldnanoparticles in the size ranges of 2.5-27.5 nm and 1.25-17.5 nm with an average size of 10 nm and 3 nm, respectively.The prepared colloid gol...
Introduction: A main choice for cancer treatment is radiotherapy. But, the radiotherapy disadvantage is damages caused by radiation given to normal tissues/organs surrounding cancer. One way to avoid this is via increasing radiosensitization of cancer cells. Gold nanoparticles (GNPs) have shown sensitizing effect on cancer cells by enhancing their absorbed dose. Unlike earlier ...
